Free SEO & Social Tools
Control how pages appear everywhere they're unfurled: build valid JSON-LD for Google rich results, audit any URL's meta tags with a scored report, and preview link cards across LinkedIn, X, Slack, Discord, and Facebook before you share.
Schema.org JSON-LD Generator
Build valid structured data for Google rich results
FAQ, Product, Event, Organization, Article and more. Real-time split editor with client-side validator. Copy or download JSON-LD.
OpenGraph Preview Tester
See how your link looks on LinkedIn, X, Slack & more
Preview link cards on LinkedIn, X, Slack, Discord, and Facebook. URL fetch or paste HTML. Detects missing OG tags with fix snippets.
Meta Tags Analyzer
Audit SEO, OG, Twitter Card, and JSON-LD meta tags for any URL
Enter any URL to fetch and analyze its HTML meta tags. Checks SEO (title, description, canonical), Open Graph, Twitter Card, technical tags (viewport, charset, hreflang), and JSON-LD structured data. Scores 0–100.
🧾 Validate before shipping
Invalid JSON-LD is silently ignored by Google. The generator validates as you type, so what you copy is what gets parsed.
🖼️ OG images are the click
Links with a correct og:image get dramatically more engagement. Preview every important URL — each platform crops differently.
🔍 Audit competitors too
Run the meta analyzer on pages that outrank you. Their structured data and tag choices are public — learn from them.
FAQ
Which schema types does the generator support?
FAQ, Product, Event, Organization, Article, and more — each with a guided form, live validation, and copy-ready JSON-LD. Individual guides exist for every type.
Does schema markup guarantee rich results?
No — valid markup makes you eligible; Google decides per-query. Invalid markup guarantees you won't get them, which is why validation matters.
How does the meta tags analyzer fetch my URL?
Through a lightweight proxy worker that fetches the page HTML so tags can be read — the URL isn't logged, and paste-HTML mode skips the network entirely.
Why does my link preview look different on each platform?
Each platform reads different tags with different fallbacks and crops images to different ratios. The OG tester shows per-platform renderings so you catch this before posting.
